Gregory McRoberts designed his augmented reality specs to look like an angry eyepatch. Apart from serving as a cool disguise for Halloween, it was designed as a aid for the visually impaired. Instead of an LCD screen to show information, the patch uses a simple set of glowing LEDs to translate temperature and distance information to the wearer, helping provide depth and safety cues to those without 3D vision.

A flashing green LED will blink faster or slower depending on whether an object is closer or farther away. Blue LEDs will shift to red if an object or a room is above 80 degrees Fahrenheit.

Gregory also suggests that the device could be fitted with vibration motors to provide similar feedback to the totally blind.
